03 GMC Envoy reduced engine light is coming on truck only goes 30 mph; is this an oxygen sensor???

While driving down the road a light comes on that reads REDUCED ENGINE POWER and the truck will only go about 30 mph. If you turn the truck off and restart it then its fine. At times when Im at a stop light it will die also. Is this the oxygen sensor????

Is your check engine light on? If so have the computer
scanned and post the trouble codes. Advance and
Autozone auto parts stores will do it for free. Sounds like a
problem with the traction control system. HTH. -
